In 2013, Rebecca, then 12, couldnt stand it anymore. She jumped to her death near her home in Florida. Soon afterward, Trisha Prabhu read about the story. “I was surprised and heartbroken，” says Trisha, now 15, who is from Naperville, Illinois. “I knew that I had to do something to stop this from ever happening again.”Trisha did some research. Studies show that one fourth to half of all teens in the US. have been cyberbullied (网络欺凌). Experts say that if you are ever bullied online, you should tell a trusted adult. Tell the cyberbully to stop, and prevent him or her from contacting (联系) you again. Print and save messages to share with the police. This is good advice, agrees Trisha. But these methods all take place after the bullying has already happened. Trisha had a different idea. Why not teach cyberbullies to stop before they post these messages?Trishas research who awards, including a prize in the Google Science Fair. Then, Trisha built the ReThink app (应用软件). It is programmed to recognize words or phrases that could be hurtful. When that happens, different warning messages come out. “Dont say things that you may regret later！” says one message. Others ask, “Are you sure you want to say this？” and “Are these words really you？”Now Trisha is working on a version (版本) of ReThink for computers.“Im a big dreamer，” she says. “I want to stop cyberbullying before the hurt is done.”【文章大意】本文是记叙文。为了防止同龄人受到网络暴力的威胁，一个美国女孩设计出了一款名为ReThink的应用软件。1What do we know about Rebecca Sedwick?A.
